FIG. 4 is another partial diagram of the child restraint base 11 according to the embodiment of the present invention. FIG. 5 is a diagram of a third panel component 115 according to the embodiment of the present invention. As shown in FIG. 2 to FIG. 4, the child restraint base 11 includes a base body 111, a first panel component 112, a second panel component 113, the anchor belt 114, the third panel component 115, a first anchor 116, a second anchor 117, a first pocket 118, a second pocket 119, a first cover 11A and a second cover 11B. The base body 111 is for mounting the child restraint carrier 12. A first passage 1111 and a second passage 1112 are formed on two rear lateral sides of the base body 111 for allowing the anchor belt 114 or a vehicle belt of the vehicle to pass therethrough. The first panel component 112 is disposed on the base body 111. A first through slot 1113 is formed between the first panel component 112 and the base body 111. The second panel component 113 is disposed on the base body 111 and spaced apart from the first panel component 112. A second through slot 1114 is formed between the second panel component 113 and the base body 111.

The anchor belt 114 passes through the first through slot 1113 and the second through slot 1114 and is slidable between the in-use position and the stored position along the first through slot 1113 and the second through slot 1114. The third panel component 115 is pivotally disposed between the first panel component 112 and the second panel component 113 and pivotable between an opened position and a closed position relative to the base body 111 for removing slack from the anchor belt 114 or the vehicle belt. The first anchor 116 and the second anchor 117 are connected to two ends of the anchor belt 114 and for connecting with the vehicle. The first pocket 118 and the second pocket 119 are located on an outer perimeter of the base body 111 and located at two front lateral sides of the base body 111. The first pocket 118 is for receiving the first anchor 116 when the anchor belt 114 is moved to the stored position and has a first top opening 1181 for easy access. The second pocket 119 is for receiving the second anchor 117 when the anchor belt 114 is moved to the stored position and has a second top opening 1191 for easy access. The first cover 11A is pivotally connected to the base body 111 and for covering the first top opening 1181. The second cover 11B is pivotally connected to the base body 111 and for covering the second top opening 1191.

Specifically, a first step-shaped structure 1115 and a second step-shaped structure 1116 are formed on the base body 111. A protruding length of a lower portion of the first step-shaped structure 1115 is less than a protruding length of an upper portion of the first step-shaped structure 1115. The protruding length of the first step-shaped structure 1115 can be decreased from the upper portion of the first step-shaped structure 1115 to the lower portion of the first step-shaped structure 1115 gradually. A protruding length of a lower portion of the second step-shaped structure 1116 is lower than a protruding length of an upper portion of the second step-shaped structure 1116. The protruding length of the second step-shaped structure 1116 can be decreased from the upper portion of the second step-shaped structure 1116 to the lower portion of the second step-shaped structure 1116 gradually. The first step-shaped structure 1115 and the second step-shaped structure 1116 are respectively covered by the first panel component 112 and the second panel component 113. The first through slot 1113 is formed between the first step-shaped structure 1115 and the first panel component 112, and the second through slot 1114 is formed between the second step-shaped structure 1116 and the second panel component 113. Furthermore, a first inner protruding rib, which is not shown in the figures, protrudes from the first panel component 112 downwardly and located at a position corresponding to the lower portion of the first step-shaped structure, and a second inner protruding rib 1131 protrudes from the second panel component 113 downwardly and located at a position corresponding to the lower portion of the second step-shaped structure 1116. The first inner protruding rib and the second inner protruding rib 1131 guide the anchor belt 114 downwardly and away from the third panel component 115 when the anchor belt 114 moves from the in-use position toward the stored position. In other words, the anchor belt 14 at the stored position is not tensioned by the third panel component 115 by such configuration.

Besides, a recess 1117 is formed on the base body 111 and located between the first step-shaped structure 1115 and the second step-shaped structure 1116 for receiving the third panel component 115 when the third panel component 115 is located at the closed position, and the third panel component 115 drives the anchor belt 114 to partially enter into the recess 1117 to tension the anchor belt 114 or the vehicle belt for removing the slack from the anchor belt 114 or the vehicle belt when the third panel component 115 pivots toward the closed position. The child restraint base 11 further includes a first engaging component 11C and a second engaging component 11D. The first engaging component 11C is disposed on the third panel component 115. The second engaging component 11D is disposed on the base body 111. The first engaging component 11C engages with the second engaging component 11D for preventing the third panel component 115 from leaving from the closed position when the third panel component 115 is located at the closed position. Preferably, the child restraint base 11 further includes a resilient component 11E installed between the third panel component 115 and the base body 111 for biasing the third panel component 115 to move toward the opened position.

As shown in FIG. 2, when it is desired to use the anchor belt 114 to secure the child restraint base 11 onto the vehicle, the third panel component 115 can be operated to pivot to the opened position along a first rotating direction R1 around a pivoting shaft 1151 of the third panel component 115, and the anchor belt 114 can slide to the in-use position and pass through the first passage 1111 and the second passage 1112 to connect with the vehicle by the first anchor 116 and the second anchor 117. Afterwards, the third panel component 115 can be operated to pivot from the opened position to the closed position along a second rotating direction R2 opposite to the first rotating direction R1 around the pivoting shaft 1151 of the third panel component 115 to tension the anchor belt 114 for removing the slack from the anchor belt 114, which achieves a purpose of securing the child restraint base 11 onto the vehicle to prevent movement of the child restraint base 11 relative to the vehicle.

Please refer to FIG. 3 and FIG. 6. FIG. 6 is a partial diagram of the child restraint base 11 as a vehicle belt 2 is tensioned by the third panel component 115 according to the embodiment of the present invention. As shown in FIG. 3 and FIG. 5, when it is desired to use the vehicle belt 2 to secure the child restraint base 11 onto the vehicle, the third panel component 115 can be operated to pivot to the opened position along the first rotating direction R1 around the pivoting shaft 1151 of the third panel component 115. Afterwards, the anchor belt 114 can slide to the stored position along the first through slot 1113 and the second through slot 1114, and the first anchor 116 and the second anchor 117 can be respectively received inside the first pocket 118 and the second pocket 119. When the anchor belt 114 is at the stored position, the anchor belt 114 is far away and located below a belt path of the vehicle belt, which allows the vehicle belt 2 to pass the first passage 1111 and the second passage 1112 without interfering with the anchor belt 114. When the vehicle belt 2 passes through the first passage 1111 and the second passage 1112, the vehicle belt 2 is laid on the first panel component 112 and the second panel component 113 instead of passing through the first through slot 1113 and the second through slot 1114. After the vehicle belt 2 passes through the first passage 1111 and the second passage 1112, the third panel component 115 can be operated to pivot from the opened position to the closed position along the second rotating direction R2 around the pivoting shaft 1151 of the third panel component 115 to tension the vehicle belt 2 for removing the slack from the vehicle belt 2, which achieves the purpose of securing the child restraint base 11 onto the vehicle to prevent movement of the child restraint base 11 relative to the vehicle.

In contrast to the prior art, the present invention utilizes the first panel component, the second panel component and the base body to form the first through slot and the second through slot where the anchor belt, i.e., a latch belt, slidably passes through. When it is desired to use the anchor belt to secure the child restraint base onto the vehicle, the third panel component can be operated to pivot to the opened position, and the anchor belt can slide to the in-use position and pass through the first passage and the second passage to connect with the vehicle by the first anchor and the second anchor. Afterwards, the third panel component can be operated to pivot from the opened position to the closed position to tension the anchor belt for removing the slack from the anchor belt, which achieves the purpose of securing the child restraint base onto the vehicle to prevent movement of the child restraint base relative to the vehicle. When it is desired to use the vehicle belt to secure the child restraint base onto the vehicle, the third panel component can be operated to pivot to the opened position, and the anchor belt can slide to the stored position for allowing the vehicle belt to pass the first passage and the second passage without interfering with the anchor belt. When the vehicle belt passes through the first passage and the second passage, the vehicle belt is laid on the first panel component and the second panel component instead of passing through the first through slot 1113 and the second through slot 1114. After the vehicle belt passing through the first passage and the second passage is buckled, the third panel component can be operated to pivot from the opened position to the closed position to tension the vehicle belt for removing the slack from the vehicle belt, which achieves the purpose of securing the child restraint base onto the vehicle to prevent movement of the child restraint base relative to the vehicle. Therefore, the present invention has an advantage of easy operation.
